Patent number: 9951798Abstract: A control device includes a valve, having a body connected to the first chamber of a cylinder via a first hydraulic connection and to the second chamber of the cylinder via a second hydraulic connection. The control device includes a first hydraulic duct connected to a first actuating-fluid source, and a second hydraulic duct connected to a second actuating-fluid source. The hydraulic ducts communicate with the body of the valve. The valve further includes a distribution device that is movable within the body of the valve, between a first position, in which the distribution device places the first hydraulic connection and the first hydraulic duct in fluid communication, and a second position, in which the distribution device places the second hydraulic connection and the second hydraulic duct in fluid communication.Type: GrantFiled: January 8, 2015Date of Patent: April 24, 2018Assignee: GE Renewable TechnologiesInventor: Armin Steinhilber

Patent number: 9494173Abstract: A device controls the movement of a ring gate of a hydraulic machine between an open position and a blockage position. The device includes at least four cylinders, the rods of which are suitable for being connected to the ring gate at locations located on a perimeter of the ring gate. The device also includes at least two hydraulic members for synchronizing pistons, the hydraulic synchronization members being connected to the cylinders such as to form at least two groups. Each group encompasses at least two cylinders connected by at least one hydraulic synchronization member, two cylinders belonging to two separate groups not being connected by a hydraulic synchronization member.Type: GrantFiled: January 20, 2011Date of Patent: November 15, 2016Assignee: ALSTOM Renewable TechnologiesInventors: Robert Pavillet, Armin Steinhilber

Publication number: 20070134103Abstract: The input element comprises a body provided with openings respectively connecting to the pump, the reservoir and enabling information return to the pump. The body comprises a bore enabling communication between the openings and which are respectively joined to the pump and the reservoir, whereby a piston is mounted therein in order to establish said communication or not, whereby an extremity thereof is subjected to the pressure of the pump and the other extremity is subjected to pressure for information return and subjected to the pressure of a spring. The pressure exerted by the spring is substantially equal to the lift pressure of the pump and the piston and/or body comprise openings for communication of the chambers disposed on the pump side and reservoir side when the distributor is in rest position.Type: ApplicationFiled: October 8, 2004Publication date: June 14, 2007Applicant: Bosch Rexroth D.S.I.Inventor: Armin Steinhilber
